6 Claims.

This invention relates to ventilating and vaporizlng apparatus, and more particularly to means for efiectively vaporizing a volatile liquid, such as a deodorant, in a vehicle, such as, for example, an airplane, etc.

An object of the invention is to provide simple and effective means for supporting a vaporizing liquid within an air stream flowing, into the interior of a vehicle and controlling the extent of volatilization by removable closure means for receptacles for the liquid.

A further object is to. provide in conjunction with an air inlet through which a stream of air flows into a compartment, readily attachable means for supportinga container or containers of volatile liquid within the air stream while inter fering to a minimum degree with the inflow of fresh air.

A still further object is to provide means for quickly deodorizing the compartment through the use of a volatile liquid supportedin effective relation with a stream of incoming air, means being provided for inducing rapid and controlled vaporization.

A further object is to provide in combination with an annular air inlet, means for supporting a container or containers partially within the annular stream, whereby effective suction induces a volatilization of the liquid within the receptacles while interfering to a minimum degree with the inflow of air, and, further, providing means for increasing the suction through use of the receptacle closures when not placed upon said receptacles.

Other objects and advantages will appear as the specification proceeds.

' The invention is illustrated, in a preferred embodiment, by the accompanying drawing, in which- Figure 1 is a perspective view of apparatus i1- lustrati-ng my invention; Fig. 2, a top plan view of the means for suspending the liquid receptacles below the air inlet; and Fig. 3, a sectional detail view, the section being taken as indicated at line 3 of Fig. 2.

In the illustration given, A designates a ceiling or wall air inlet; B, receptacles for a volatile liquid, such as a deodorant; and C, means for suspending the receptacles below theair inlet.

The air inlet fitting A may be of any suitable construction. The embodiment illustrated is a type of fitting commonly employed in theceilings ofairplanes and other vehicles. Since specific claims are not directed to the structure, a detailed description is believed unnecessary. In designates a metal member secured to the ceiling or any upper wall of a compartment and providing therein an air space. i I designates-a downwardly and outwardly-extending flange which may be formed integrally with the member It Spaced inwardly from the member fl is a circular flange l2, which is secured to flange II by the spacer bars l3, thus providing an air inlet space M between the two flanges. Closing the lower end of the inner flange i2 is a glass panel I5. Usually a light bulb (not shown) is housed above the panel 15.

It will be noted that the above structure provides an annular air inlet through which an air stream may pass downwardly and outwardly into the compartment, thus effectively. furnishing ventilation. While the improved apparatus claimed herein functions extremely effectively with this type of inlet, it will be understood that other forms of air inlets may be employed.

The receptacles B may be employed singly or plurally and may be of any suitable construction. In the illustration given, each receptacle comprises a glass jar [6 having a threadedtop 11 adapted to be engaged by a threaded metal closure I 8. Within each jar is a body of vaporizing liquid, such as, for example, deodorant, or liquids for other functions, and the usual supports are provided for maintaining a wick pad at the top of the jar and communicating (not shown) wicks extending downwardly into the liquid.

The receptacle supporting means C may be of any suitable. construction. In the embodiment illustrated, metal strap arms 19 and 20 are equipped at their upper ends with means for releasably engaging the flange H. In the illustration given, the upper end of the arm [9 and of the arm '20 is folded back upon itself at 2| and threaded to receive the wing screw 22. .Welded to the innerside of strap 20 is a metal strip 23 having an inwardly-spaced clamping arm 24 at its upper end.

A similar member 23 provided with a clamping arm 24 is welded to a strap arm is, but the member extends downwardly to a greater degree than does member 23 on strap 2%.

The strap arm 19 base. lower horizontal section 25. Near each end of the section 25 is secured a bracket arm 26 having upwardly-extending ends 21. A receptacle supporting band 28 1 s welded to the upwardly-turned ends 27 and also the vertical portions of strap arm l9. Ring 23 has free ends 29 spaced apart and. threaded to receive the wing screw 31] by which read adjustment for clamping a receptacle withinthe ring is efiected.

. The strap arm 20 has an inwardly-inclined section 31 on each side and a short horizontal bottom portion 32 which is welded to section 25 of strap Within the lower portion of the inclinedsection 3! of strap arm 20 is a closure-supporting bracket 33. Each bracket is provided with upwardly-ex,- tending arms 34 having inwardly-turned flanges 35:. The bracket permits ready sliding of the closure l8 into a secure position wher the bot- 3 tom of the closure 58 rests upon the horizontal section 32 of the arm 26.

The p i g e ns is so formed as to maintain the receptacles in effective relation with the air stream whereby the vapor will be rapidly drawn off and spread through the compartment.

Should the air inlet be modified, a corresponding {annular stream of air with a central suction area between, a plurality of receptacles containing a modification must be made in the suspending means so as to bring the air stream into contact-- with the vaporizing pads. In the particular structure illustrated, unusually effective vaporization is brought about without interfering to any substantial degree with the incoming air stream:

While a portion of theair stream strikes the upper end of the receptaclesB, a substantial portion of the top of eachmember B is located within the annular stream and thus, without direct contact with the stream, is subjected to suction which induces rapid vaporization. With respect to the portion of the pad within the air stream, it will benoted that extremely rapid vaporization will take place due to the fast moving air stream. The suction referred to is enhanced by placing the closures I8 taken from the receptacles B upon the bracket arm supports 33, thus to close off or preclude the uprush of air into the hollow space within the annular air stream. At the same time, the closures are supported adjacent their recep tacles and are available for quick application to the receptacles for controlling theextent of deodorization or other vaporizing operation,

In operation, the supporting members C are clamped to the annular flange l I; the receptacles B, filled Wth deodorant or other volatile liquid, are placed within the clamping bands 28 and secured therein by bringing the ends 30 toward each other. The closures l8 are removed from the receptacles and inserted within the bracket arms 33.

The downward sweep of air from the inlet l4 strikes the outer portion of the vaporizing pads in the receptacles B and creates a suction within the hollow space enclosed bythe air stream., The

inner portion of the top of each receptacle is therefore subjected to suction, and. vaporization proceeds rapidly therefrom. With the arrangement shown, complete deodorization of a compartment, such as that found within an airplane, is accomplished within an, extremely brief period. The closure members l8 are then replaced upon the receptacles and vaporization stopped. In the resulting ventilating operation, it will benoted that the apparatus interferes to a minimum degree with the downwardly and outwardly sweeping air currents.

While in the foregoing specification, I have set forth certain specific apparatus for effecting the results indicated, it will be understood that considerable variation can be made and should be made in conjunction with different types of air inlets without departing from the spirit of my invention.
